GENERAL AIRSPEED TERMINOLOGY AND SYMBOLS
KCAS
Knots Calibrated Airspeed
for position and instrument error and expressed in knots.
Knots calibrated airspeed is equal to KT AS in standard
atmosphere at sea level.
KIAS
Knots Indicated Airspeed
airspeed indicator and expressed in knots.
KTAS
Knots True Airspeed
relative to undisturbed air which is KCAS corrected for
altitude and temperature.
Manuevering Speed
may use abrupt control travel.
Maximum Flap Extended Speed
permissible with wing flaps in a prescribed extended
position.
Maximum Structural Cruising Speed
should not be exceeded except in smooth air, then only with
caution.
Never Exceed Speed
VNE
exceeded at any time.
Stalling Speed or the minimum steady flight speed
which the airplane is controllable.
Stalling Speed or the minimum steady flight speed
which the airplane is controllable in the landing configu­
ration at the most forward center of gravity.
Best Angle-of-Climb Speed
the greatest gain of altitude in a given horizontal distance.
Best Rate-of-Climb Speed
greatest gain in altitude in a given time.
